Some other approaches such as game-theoretic, social and trust-based have also been proposed to deal with the issue of selfishness. SSAR [1]} is a social-based scheme that tackled the problem of selfishness in a network. In this approach, a node having a strong social relationship in a community can take part in data forwarding for other nodes. Lui et al. [2]} proposed an incentive scheme to share information that is related to a road accident, road construction and delay in traffic, etc. Fawaz et al. [3]} proposed Unmanned Aerial Vehicles (UAVs) scheme to encourage vehicles for cooperation. Li et al. [4]} proposed a scheme which also stimulates vehicles for cooperation in a vehicle to vehicle networks. Socievole et al. [5]} proposed a social approach to encourage selfish and misbehavior nodes for cooperation. Umar et al. [6]} proposed a game-theoretic scheme that motivates the nodes for cooperation to reduces the load on nodes. Vamsi et al [7]} proposed a trust-aware scheme to stimulate the nodes to take part in the routing process. Kumar et al. [8]} has proposed a dynamic trust-based intrusion detection scheme track and isolate the selfish nodes from the network. Pal et al. [9]} proposed a trust-based approach for ensuring the routing process. Dhurandher et al. [10]} proposed a trust-based scheme that motivates the nodes for cooperation in the network.
